(Get the code!)
That's just a workaround that manually forces MSI to be disabled. If you look at the lspci output in that other bug report, you see that MSI is also disabled for the card reader in that system:
02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device 5249 (rev 01)
[snip]
Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+
The workaround just bypasses the same erroneous line of code in the driver. The patch mentioned in this bug report is a more correct and general fix.
